Walls Disappear?

[Tyveka]

We need to create a coordinated plan view from Navisworks, so our "enforcer" can walk the job site and make sure that all the conflicts we've resolved in the model are actually being built the way we resolved them.

However, when we switch to a top down, orthographic view in Navisworks, all of the walls disappear from the model. How do we get these to show up? Or is there even any way to do so?

Thanks!

Edit - what is even more strange - when I move the cut plane up to the second floor, my walls show up on the second floor. But when the cut plane is cutting the first floor, no walls appear in orthographic projection mode at all.
Any thoughts or suggestions would be appreciated. Thanks!

Odd indeed!

I have one job where everything disappears as I approach an east orthographic view (not west though).

I haven't figured that one out yet...
